Ojai, CA 93022 Frost Dates
Ojai, CA: when does the frost end?
The last spring frost here typically falls around 03/21, about 205 days from today. Fall's first freeze usually shows up around 11/15, roughly 235 days after the last spring frost.
Zone 9b (25 to 30°F average annual minimum) comes from the USDA Plant Hardiness Zone Map; the frost dates above are the 1991-2020 normal at the nearest reporting NOAA station for Ojai, not a forecast for this year.
Stretching the season past the first frost
With roughly 11 weeks until Ojai's first fall frost, a row cover or cold frame is what stretches the last few weeks of harvest here.
How much risk comes with planting early here
03/21 is the middle of 30 years of NOAA records, not a promise. Getting tender plants in by 02/20 carries real risk, frost has hit that late in about 9 of 10 years here. Wait until 04/15 and only about 1 year in 10 sees frost after that.
